Abstract:- Photonic crystal fibres (PCFs) is attracting more attention nowadays as a promising platform for communication chemical sensing and measurements. A spiral PCF structure is made of silica material is proposed where the core is defined as solid. Utilizing the finite element method (FEM) has numerically investigated waveguide properties. The PCF characteristics such as normalized frequency, mode field diameter, effective area, nonlinearity, and confinement loss are investigated. The ultra-low confinement loss is achieved at a 1.55μm wavelength. The high nonlinearity 7W-1km-1 at 1.55μm wavelength is achieved. The ultra-high birefringence 0.84065×10-2 is achieved at a 1.5 μm wavelength.

Keywords: - Photonic crystal fibre, confinement loss, nonlinear coefficient, effective area, normalized frequency.
